Abstract

The utility model provides a tubular hot water heater, including the casing, the inside inner tube that is provided with of casing, inner tube connection have water inlet and delivery port, still are provided with steam inlet on the casing, wholly at casing internal heating inner tube medium, are provided with the comdenstion water export after the steam cooling on the casing. Tubular hot water heater, be the tubular heat exchanger that the inner tube walked cold water, the utility model discloses require lowly for external foreign particle under the prerequisite of the same heat transfer.

Description

Tube type hot water heater

Technical Field

The utility model relates to a heater relates to a tubular hot water heater particularly.

Background

At present, the small-sized plate type hot water heater on the market is low in appearance and large in occupied area. The internal plate is thin and flexible, so that the requirement on impurity particles of water and steam to be drained inside is high, and the pressure used in practical application cannot be higher than the design pressure due to the fact that the plate is thin and the ethylene propylene diene monomer rubber gasket is arranged between the plates for sealing. Economically, the small plate-type hot water heater has higher requirements on environment and sanitation and higher cost. In the material, a stainless steel plate is applied, the metal is more, the cost is higher, and the like. It was decided to autonomously research and develop a tube heater to replace the small-sized plate type hot water heater currently on the market.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that the problem that exists among the prior art is overcome, a tubular hot water heater is provided.

In order to solve the above problems, the technical solution of the present invention is as follows:

a tubular hot water heater comprises a shell, wherein an inner tube is arranged in the shell, the inner tube is of a plurality of parallel structures, one end of the inner tube is provided with an upper tube plate, and the other end of the inner tube is provided with a lower tube plate and an inner sealing head; the inner pipe is connected with a water inlet and a water outlet, the water inlet is connected with one half of the inner pipe to serve as a water inlet pipe, the water outlet is connected with the other half of the inner pipe to serve as a water outlet pipe, and the water inlet pipe and the water outlet pipe are communicated at the inner end socket; the shell is also provided with a steam inlet, steam heats the medium in the inner pipe in the shell, and the shell is provided with a condensed water outlet after steam cooling.

The steam inlet is arranged at the high position of the shell, and the condensed water outlet is arranged at the low position of the shell.

The inner pipe is of a floating head type, namely the water inlet end and the water outlet end of the inner pipe are fixed with the shell, and the other end of the inner pipe can freely move relative to the shell.

Advantageous effect, tubular hot water heater, be the tubular heat exchanger that the cold water was walked to the inner tube, the utility model discloses require lowly for external impurity particle under the prerequisite of same heat transfer.

Drawings

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments;

fig. 1 is an exploded schematic view of a tubular hot water heater according to the present invention.

Fig. 2 is a schematic sectional structure view of a tubular hot water heater according to the present invention.

Fig. 3 is a schematic view of the water flow heat exchange of the tubular hot water heater according to the present invention.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.

Referring to fig. 1, 2 and 3, the solution consists in a tubular heat exchanger with low requirements for various cost, environmental, sanitary, cold and hot fluid particles. Therefore, the tubular hot water heater of the utility model is available; the material is stainless steel 316L.

The upper end enclosure 5 and the upper flange 3 are welded into a whole to form a material inlet and outlet assembly body, the lower flange 2, the shell 1 and the lower end enclosure 6 are welded into a whole to form an outer tube assembly body, and the upper tube plate 7, the inner tube 10, the lower tube plate 8 and the inner end enclosure 9 are welded into a whole to form an inner tube assembly body. The inner pipe assembly body is firstly arranged in the outer pipe assembly body, then the sealing ring 4 is arranged in a sealing ring groove of a flange on the material inlet and outlet assembly body, and finally the material inlet and outlet assembly body is integrally closed and screwed down by using an M16 screw. The upper part of the shell 1 is provided with a steam flange 11.

The water inlet and outlet of the inner pipe are movable joints 12, and the upper flange 3 and the lower flange 2 are connected through inner hexagonal bolts.

In the heat exchange process, water enters and exits from the same side of the inner pipe, steam enters the outer pipe side, condensed water exits from the outer pipe side, and indirect heating of water is realized by the heating inner pipe.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
